The MIFARE Classic card activation follows the ISO/IEC 14443 Type A. After the 
MIFARE Classic card has been selected, it can either be deactivated using the 
ISO/IEC 14443 Halt command, or the MIFARE Classic commands can be performed. For 
more details about the card activation refer to 

All MIFARE Classic commands use the MIFARE CRYPTO1 and require an 
authentication.

All available commands for the MIFARE Classic are shown in 

 

All commands use the coding and framing as described in 

 and 

 if not 

otherwise specified.

The timing shown in this document are not to scale and values are rounded to 1 

μs. 

All given times refer to the data frames including start of communication and end of 
communication, but do not include the encoding (like the Miller pulses). 

Consequently a data frame sent by the PCD contains the start of communication (1 
“start bit”) and the end of communication (one logic 0 + 1 bit length of unmodulated 
carrier). 

A data frame sent by the PICC contains the start of communication (1 “start bit”) and the 
end of communication (1 bit length of no subcarrier).
